Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed August 2, 1915. Serial No. 43,207. I

To all whom it may concern:

Be it known that I, ENooH MinLnu, a citizen. of the United States, residing at Export, 'in the county of Westmoreland and State, of Pennsylvania, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

This invention relates to brushes and more particularly to that .class of brushes which are employed in surface scraping and while the invention is designed primarily for embodiment in a brush for use in cleaning meat blocks, the principles of the invention may find embodiment in various types of brushes as for example such as are employed in dressing stone or n scrubbing or scouring metal surfaces.

Brushes of the general class above referred to are ordinarily provided with wire bristles or abrading elements but after brushes soconstructed have been used for a comparatively short time the tips or ends of the said bristles or abrading elements become worn smooth and round and the brush then becomes useless. Due to the peculiar character of the abrading elements it is impractical to conveniently repoint 'or sharpen their tips and the present invention therefore aims to provide in a brush of the general class referred to, abrading elements of such characters as to permit of' said elements being sharpened whenever they become worn. Therefore a brush embodying the principles of the present invention may be used until its abrading elements have been so shortened by repeatedsharpening as to be unfit for further use. Another aim of the invention is to provide a brush of the class mentioned of such construction that the abrading elements may be readily removed and consequently renewed whenever they become worn too short for use or become broken.

The invention further contemplates forming the back of the brush in a plurality of sections and providing means for holding the sections assembled, which meansmay be readily manipulated to permit of the sections being disassembled so that the abrading elements carried by each section may be readily and conveniently sharpened.

In the accompanying drawings: Figure 1 is a perspective view of the brush embodying the present invention; Fig. 2 is a ver-' tical longitudinal sectional view through the 2 brush; Fig. 3 is a perspective view of one of the sections of .the back and one of the abrading elements; Fig. 4 is a view similar to Fig. 1 illustrating a slight modification ofv the invention; Fig. 5 is a longitudinal sectional view through the structure shown in Fig. 4; Fig. 6' isa perspective view of one of the sections of theback of the form shown in Figs. 4 and 5.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In both forms of the invention illustrated in the drawings the brush back is formed of a plurality of sections each of which carries a series of abrading elements and means is provided for holding the sections normally in assembled relation. Each section of the back of the brush shown in Figs. 1, 2 and 3 of the drawings comprises a body 1 which is preferably rectangular and of greater length than thickness, and while these sections may be formed from any suitable material it is preferred that they be made of wood. Each body 1 is formed in its under side with a longitudinal series of sockets 2 which sockets may have cylindrical walls or walls of some other contour if desired. The abrading elements are each formed from a strip of resilient sheet metal and these strips are bent upon themselves at a point midway between their ends as indicated at 3 so as to provide resilient abrading fingers 4; of equal length. The bend 3 is not an acute bend but, on the other hand, is so formed that this portion of each abrading element when inserted into one of the sockets 2 will require to be crowded into the/socket and will be held frictionally therein, the fingers 4: having a tendency to spring apart and being, as stated, resilient. The manner in which the abrading elements are fitted into the sockets is clearly illustrated in Fig. 2 of the drawings, and it willbeobserved that the said elements are so positioned that their fingers 4: will be in front to rear alinement when the sections a} of the vback areassembled to form the complete brush.

The strips 4; are here illustrated as rem-f tively narrow, but it will be understood that they may be of any desired width and that if desired. the abrading elements at their bends 3 may be of greater or less width than.

the fingers 4.! It will further be apparent that several of the abrading elements in nested relation may be inserted within each of the sockets 2 if desired.

As above explained the sections of the back are to be assembled to complete the brush back and when so assembled they are I held together by means to be now described received within the recesses 5'anda num-' ber of the sections suflicient to fillthe-frame are placed. therein. Each side 6 of the frame is provided at its 'free'end with a head 8 havinga shoulder 9 and engaged with the said ends of" the side members 6are rec-' tangular loops 10 formed at the outer ends of links'll'the' ends of the loops engaging against w the, shoulders 9 in the manner clearly shown in Fig. 1 0f the drawings.

The inner ends ofthe links 11 are hooked as indicated at 12 and engaged in openings 13 formed in a plate 14. The plate 14 is provided with a threaded aperture 15 through which is threaded a clamping screw 16 hava milled head 15 providing means whereby the screw may be readily adjusted. The end of the screw bears against a plate 18 which is disposed against the side face of the end one of the series of sections and it will be understood that by adjusting the .clamping screw the sections may be firmly bound together, the connecting portion of the frame engaging of course against that one of the sections located at the other end' of the series of sections. Of course when iti's desired to disassemble the sections the clamping screw 16 is loosened and the loops 10 are disengaged from the heads 8 whereupon the sections may be slidfrom the frame. It will be apparent that the up.- per and lower walls of the recessesfi, contacting with the upper and lower edges of the sides 6 of the frame, serve to hold the sections against relative displacement and in proper'alinement. .When, it is desired to sharpen the points -.-or extremities of the abrading fingers 4B, the individual sections are grasped and thep oints of the said fingers 'are heldagain'st' a grindstone or are the ends of first one of the setsof fingers and then the ends ofthe other set of fingers to the grindstone or other sharpening dev1ce'.' f In that form of the inventionshown in sharpened in any other suitable manner and inasmuch as each section of the back sup- .ports a single longitudinal series of abrading elements the elements may be readily and conveniently sharpened by presenting Figs. 4, 5 and 6 of the drawings the sections of the backare indicated by the numeral. 19

and are held together in assembled relation to securely bind the sections together." The i sockets in the sections 19 are indicated by r the numeral 25 and one or, more of the abrading elements is fitted into each ofthe sockets, in substantially the. same manner as the previouslydescribed form of the invention.- In the present form,qhowever, the abrading elements are securely anchored within thesockets in a manner to. be now described. Each sectionis' formed in its under side with a longitudinally extending groove 26 which is relatively narrow and deep and this groove transects the sockets 25 of the series. After the abrading elements have beenffittedinto the sockets a.

locking strip 27 is fitted intothe groove 26 and extends within the bight'sv of the said abrading elements in thezinanner clearly shown in Fig. 5. This strip may be held solely by friction or if desired 'may be securely heldin place bymeans of staples or other suitable fastening elements 28.

. Having thus described the invention,

what is claimed as new is:

1. A brush of the class described includ- 7 ing a frame open at one'end, a. back. comprising a plurality of sections assembled within the frame, abrading elements carried bythe sections, a plate located at the open end-ofthe. frame, connection between the plate and the sides of the frame at the said open end thereof, and a binding screw threaded through the said'plate and adjustable to bind the sections together within the frame. 1 Y. v V 2. A brush of the classdescribed including a frame openat one end, a plurality of 5 frame, a plate arranged at the open end of the frame, connection between the plate and the sides of the frame at the open end thereof, a bearing plate arranged at the open end of the frame, and a binding screw threaded through the first mentioned plate and bearing against the said bearing plate and adjustable to bind the sections together within the frame.

In testimony whereof I afiix my signature.
